Day 2: It’s really dark in here…

Since this is your first piece of new code, we’ve included two versions
to prove an important point. One with comments, and one without. They
are 100% functionally equivalent.
Comments are ignored by the
compiler and are a feature useful to YOU to help make code more
readable. It may look long and daunting, but it’s mostly just useful
information for you to read.
When you remove all the comments, it becomes a LOT smaller, but with
less potentially useful information for the developer (you!)
The exact same code without comments:
TL;DR: Don’t be afraid of comments! Good programmers use comments. Start good habits and try adding some yourself!


Can anyone tell me why this doesn't save progress after closing the program. Each re-entry I have to go through and check off the Starter vids & the 0 & 1 courses?
I am signed in (hence name attached to comment), so I would assume my progress would be saved/tracked as well.
@Patrick Flood Maybe your browser is preventing the storage of cookies?
Hello. Is happening since changed to CraftingTable. I don't know how to fix it. I sent a comment about it but until now no answer. Is annoying.
the light wont light up
@John Thomson PLS HELLLLLLLLLLLLLLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPPPPPPPPPPP
are you sure it's wired correctly?
@John Thomson Please check your connections carefully. A mistake I had a habit of making was to read the inputs on the HERO board incorrectly.and try to use input #13 instead of input #12.Also, I wouldn't have the LED oriented correctly. Took me several tries to get it right.
@John Thomson It didn't for me at first. I jiggled the LED in the breadboard and it lit up. Breadboards aren't always entirely reliable. So jiggle the LED a little, and/or the resistor and the wires, to make sure they're properly seated.
in the DUINO app what it the cabin lights code under?????
it says "we've included the comments in the code" but I don't understand where the code actually is. Is it saved in a file that I have? I just looked at what you had typed and recreated it from scratch, it worked fine, but it seems like im missing some referenced documents somehow.
re-run the video, and listen and watch closely. I had to rewatch a few times and pause several times and back up on some items but eventually cathered all the information I needed. However I am 60 and things don't come to my understanding as well as they use to.but the comments are at the ends of the code after the // from my understanding.
@John Thomson look closely at the pin connections to make sure they are inserted in the correct hole. they are close together and easy to miss.Did you make sure the Arduino is being seen by the program by checking the Board and COM port in the tool file?

@EDO BaPa Same issue here - Crafting Table this is your bug, not ours.
can I separate the rainbow wires
?
@Addison Schairer Yes, they pull apart.
Although it was not mentioned here and as a good practice, you should use wire cutters to remove the resisters from the tape strips. You will lose some of the lead, but you also avoid leaving any of the glue residue on the resister, which can interfere with the connection.
@T Morkovsky that's what I did and it turned out fine
@Jason Puehler thank you
@Addison Schairer Yes, you'll need to. I expect by the end, all of them will be separated.
I have exactly what they have written written down, but it’s saying that the pinMode was not declared
@Geraldo Rivera search “arduino IDE on your search engine
i cant find my code in arduino on lesson 2
Is she ok? She seems like she needs help.
I cant find the code either
Fyi, if you're having an issue like I did with the led not lighting up, try changing out the wire. One of the wires I chose was faulty. Took me an hour plus to figure it out, and it wasn't even me who figured it out.
Where is the code on the website.
hiithisisyourmom
I dont understand how Alex got to the premise code because I don't see it anywhere
Please help
Premade not premise
how do you get the program
Just a tip: don't rest the Hero board on top of the wrapper it comes in. The wrapper is conductive and can cause a short, at the very least causing the LED not to blink, and maybe worse.
@Sara Trammell Are you sure you did not add an extra zero? If not, I suggest unplugging everything from the board and trying again.
hello, this is my first time doing something like this and i couldn't figure out how to paste the code for day 2 into the arduino ide. I someone would please explain to me what i should do i would very much apriciate it.
Cabin lights on!
copy and paste the code above on arduino in a new file
The links to the Mission Resources is broken, so there is no was to access the sample code or other resource that are supposed to be available. Crafting table please get these fixed
@kane bray you have to type it for now because the links to the Mission resources is broken
@Patrick Flood This might be a silly question but are you clicking the "continue and complete" button? It doesn't automatically save your progress, only if you use that button. I clicked a few videos before I figured that out.
